Before You Begin

Remove the following parts before you begin:

Tools

  • ESD-safe tweezers

  • Kapton tape

  • Nylon probe (black stick)

  • Torx T3 screwdriver

  • Touch ID alignment kit

Caution

This procedure requires System Configuration. After you’ve completed all removal and reassembly steps, learn how to initiate the System Configuration process.

Important

This procedure may require a Touch ID board shim kit, which only comes with a replacement Touch ID board. It’s not a separate orderable part.

Removal

  1. Use ESD-safe tweezers to loosen the adhesive on the Touch ID board flex cable. Fold the flex cable back from the Y-shaped cowling to expose the Touch ID board flexible cowling.

  2. Use the T3 screwdriver to remove the two T3 screws (923-06940) from the Y-shaped cowling.

  3. Use ESD-safe tweezers to remove the Y-shaped cowling from the top case. Save the cowling for reassembly.

  4. Use the T3 screwdriver to remove the two short T3 screws (923-06942) (1) from the Touch ID board flexible cowling. Then use the T3 screwdriver to remove the four long T3 screws (923-06942) (2) from the Touch ID board flexible cowling.

  5. Use ESD-safe tweezers to remove the Touch ID board flexible cowling from the top case. Save the flexible cowling for reassembly.

  6. Tilt up the corner of the top case as shown. Then guide the Touch ID board flex cable out through the slot in the top case to remove the Touch ID board.

    • Important

      • If the Touch ID board wasn’t clicking properly before removal, continue to removal step 7 to remove the Touch ID shim.

      • Ensure that your work surface is clean. Under the Touch ID board is the Touch ID shim, which is a small circular part. If it falls, you can more easily find it on a clean surface.

      • If you’re using the existing Touch ID shim, skip to reassembly step 1.

  7. Place the computer right side up. Spread the tips of the pointed ESD-safe tweezers and use one tip to remove the shim from the circular recess under the Touch ID board.

    • Note: The shim has a small amount of adhesive and may stick to the top case.

Reassembly

Important

If you are replacing the Touch ID shim, follow reassembly steps 2 through 5. If you’re using the existing shim, skip to reassembly step 6.

  1. Place the computer right side up.

    • Caution: Ensure that you place the computer on a clean surface to avoid damaging internal parts.

  2. Use the pointed ESD-safe tweezers to pick up the medium Touch ID shim from the shim kit.

    • Note: The shim is black on the adhesive side and silver on the opposite side

  3. Align the Touch ID shim in the recessed circle in the top case with the adhesive side down.

  4. Press the Touch ID shim to adhere it to the top case.

  5. Stand the top case on its side as shown.

  6. Route the Touch ID board flex cable through the slot to position the Touch ID board in the top case.

    • Important: If you’re installing a replacement Touch ID board, don’t remove the blue protective liners yet.

  7. Place the top case right side up.

    • Caution: Ensure that the Touch ID board flex cable is tucked under the top case to avoid pinching the flex cable.

  8. Remove the blue protective liner on the Touch ID button.

  9. Set two Y-shaped alignment tools against the Touch ID button as shown. Secure the Y-shaped tools with Kapton tape.

  10. Place the top case upside down.

  11. Use ESD-safe tweezers to position the Touch ID board flexible cowling as shown.

    • Important: Ensure that the Touch ID board flexible cowling is installed right side up.

  12. Use the T3 screwdriver to partially reinstall the two center T3 screws (923-06942) (1). Then use the T3 screwdriver to reinstall the four outer T3 screws (923-06955) (2).

  13. Place the computer right side up and remove the alignment tools.

  14. Press the Touch ID button to ensure that you can feel it click.

  15. Turn the top case upside down. Use the T3 screwdriver to fully tighten the two center screws. Then ensure that the Touch ID button still clicks when pressed.

    • Important

      • If the Touch ID button feels too loose, repeat removal steps 4 through 7. Then repeat reassembly steps 2 through 13 with a larger Touch ID shim.

      • If the Touch ID button feels too stiff or doesn’t click, repeat removal steps 4 through 7. Then repeat reassembly steps 2 through 13 with a smaller Touch ID shim

  16. Turn the top case right side up.

  17. Look directly over the Touch ID sensor. The spaces on each side should appear equal, and the Touch ID sensor should align with the function keys. If the gaps around the sides are unequal, repeat reassembly steps 11 through 14.

  18. Turn the top case upside down.

  19. Use the ESD-safe tweezers to position the Y-shaped cowling in the top case.

  20. Use the T3 screwdriver to reinstall the two T3 screws (923-06940) into the Y-shaped cowling.

  21. If you’re installing a replacement Touch ID board, remove the blue protective liner under the Touch ID board flex cable.

    • Important: Leave the other blue protective lining on the end of the Touch ID board flex cable until you have reinstalled the logic board.

  22. Gently run the flat end of the black stick along the length of the Touch ID board flex cable to adhere it to the Y-shaped cowling.
